CVE-2026-93763 is a medium-severity vulnerability rated 6.5/10 on the CVSS scale. A protection mechanism failure in the object-document mapper's encryption configuration generation can cause fields that an application declared for client-side field-level encryption to be written and kept in cleartext, without any error or warning. A party holding ordinary read access to the database can then read values that were intended to be protected from that party.
